SPOILER ALERT! "LOST" found its way deep in the forest above Pearl City today at the old Waimano Home complex. The area is known today mostly for great ridge and valley hiking, and the drab buildings — formerly a mental institution — now house offices for the state's public safety and health departments. As it turns out, the drab, decrepit concrete structures were exactly the look "LOST" was going for. The scene being filmed takes place in a hospital maternity ward, but the mood was anything but joyous.

Wardrobe seemed decidedly rooted in the 1950s, from the hospital staff to the dapperly dressed men and women scattered around the set. One of the main faces was familiar, the other was not. Nestor Carbonell (the much-missed Richard Alpert) was spotted, looking especially stylish in a suit. But the center of attention was a distraught woman in her 20s. I have no idea who the actress was, but her character's name may ring a bell: Emily.

Emily who? Well, it would be one of the (real, not TV) nurses who would help connect the final dots, just mentioning offhand one of the babies on the set today. A baby whose adult incarnation was apparently expected to be on the scene tomorrow. And a baby whose mother we have seen before... just much, much older: Emily Locke. Yes, the very one who sold her son out, and who also spent some time in Santa Rosa.

Imagining the eerily ageless Richard Alpert off-island in the 1950s is amazing enough. But could it be that he was there for John Locke's birth? The mind boggles.

With Paul Edwards in the director's chair, my guess is that this is all for Episode 4x11.
